- Types of muscles
- Skeletal (voluntary)
- Make up bulk of body muscle tissue
- Responsible for movement e.g. biceps and triceps
- Striated with conscious control
- Has a regular arrangement so contraction occurs in one direction
- Has rapid but short contractions
- Fibres are tubular and multinucleated
- Make up bulk of body muscle tissue
- Cardiac
- Found in the heart and is myogenic
- Specialised striated with involuntary control
- Cells branch & interconnect resulting in simultaneouscontraction
- Intermediate contraction and length of contraction
- Fainter striations than skeletal, fibres are branched and uninhcleated
- Smooth muscle (involuntary)
- Found in walls of hollow organs(stomach, gall bladder) and blood vessels and digestive tract where peristalsis moves food along the gut
- Nonstriated appearance
- No regular arrangement as different cells contract in different directions
- Slow contractions but can remain contracted for a while
- No cross striations, fibres are spindle shaped and uninucleated
- Skeletal (voluntary)
